The takePicture() function captures an image.The callback occurs when the picture has been captured and encoded. You aren't seeing the callback in your app because you haven't started preview mode. It cannot be used to capture an image from another application.
Even this did work, it doesn't necessarily mean the the user has taken a picture. It could be an application like a barcode scanner or OCR that is capturing an image for analysis. I think you want to look at MediaStore. It might broadcast an intent when new media is added, or perhaps you can wake up periodically and scan for new images that have been added since the last time you scanned the database.
